10 all whom t may concern): l

Be it known that l, DANIEL P. BUCKLEY, a citizen ot the United Sta-tesof America, and resident of Fitchburg, in the county of lVorcester andState ot Massachusetts, have invented new and useful improvements m SawFrames, ot' which the following is a specilication.

This invention relates to frames for supporting saw blades andparticularly to that type li'nown as buck-saws. Objects or the inventionare to produce a frame which 1s stronger and more rigid than the usualtype of saw trame, which can be manu'tactured at a low cost and beeasily assembled, and which does not have the usual tendency` ofbuck-saw frames. to collapse when the tension on the blade is relieved.

ln order to illustrate the inventiom kone concrete embodiment thereof isshown in the accompanying drawinga in which Fig. il is a sideelevational view of `a sawT trame embodying the features loli theinvention; and w Fig. 2 is an enlarged perspective view or one of thejoints of the trame;

The embodiment of the inventio-n s hown for the purpose of illustrationcomprises a buck-saw in which the blade c is supported in the usualmanner as by pins m and m in the two end members Z) and c of the trame,the member being longer than member c to provide the usual handle n.

lnterposed between the end members Z) and c in spaced relation to bladeL 1s au cross-piece d. The cross-piece Z 1s held 1n abutting`relationship with end members 7) and c/by loops c and c which arepreterably constructed of heavy wire bent to shape with the abuttingends welded together. To prevent the loops e from moving alongcross-piece (Z andmembers b and c they preferably seat in recesses 7c, Zand Z therein and are further held on the end members by suitableretainers such as staples j and 7" which prevent the loops from beinglost when the frame is disassembled.

Member Z) is also connected to cross-piece (Z by a tension member Thismember may comprise a. headed rod passing through a hole cl in the endof cross-piece d remote from member I). After passing through opening drod f is bent as shown and the free end thereof passes through anopening By tightening turn-buckle 7u. the lower end of end member c isswung outwardly there-y by putting tension on the blade a. As the bladeis tensioned, the upper 'end of end 'I member Z; swings slightly to theright thereby tensioning rod f to substantially the same degree asrod g.ln this way, the parts are vder-any desired tension. y

rJ'he ends ot the* Pross-piece are not mortis'ed! into the end membersbut are merely held in abutting relationship. Thus the connectionbetween the cross-piece and each of the' end members constitutes a slip'con-` nection which permits the cross-piece to slip slightly on the end-members while the blade is being tensioned, thereby to wedge the endsof the cross-piece into the loops c and c. inasmuch a-s-the necessity ofrecessing the end members to receive the ends of the cross-piece iseliminated by the present construction, the endi members are thusstronger and less liable to break at the ends of the cross-piece.

I claim: l

l. A saw trame comprising two end members and a cross-piece, the ends ofthe crosspiece being constructed and arranged to abut said members, andmeans' connecting both` ends of the cross-piece .to each end memberl to-form a rigid structure.

'2. A saw lrame comprising two end mem-` bers and a cross-piece, theends of the crosspiece being conmruoted and arranged to abut saidmembers, and spacedmembers on said end members engaging opposite ends ofsaid cross-piece to 'form a rigid truss structure. y

3. A saw trame comprising two end members and a cross-piece5 a loopconnection between each end member and the adjacent end or' thecross-piece, and tensioning means extending from each end member to theend of the cross-piece remo-te therefrom.

rigidly braceditogether with the-blade un- 4. A sawframe comprising twoend members and a. cross-piece, the ends of the crosspiece beingconstructed and arranged to abut said members, a loop connection betweeneach end member and the adjacent end of the cross-piece, and tensioningmeans extending' from each end member to the end of the cross-pieceremote therefrom.

5.v A saw frame comprising' two end members andl a cross-piece, a loopon each end member for making' a slip connection with the adjacent endof the cross-piece, and a tensioning; member on each end memberengaging' the end of the cross-piece remote therefrom, thereby forciblyto retain the ends of the cross-piece in said loops.

G. A saw frame comprising two end members and a cross-piece, the ends ofsaid crosspiecebeing adapted to abut said members obliquely, loops onsaid members arranged lto encircle the ends of said cross-piece, and

piece in spaced relationto said loops tor wedge and retain they endsthereof in said loops.

i `8. A saw frame comprising spaced members, a orossepiece engaging saidmembers intermediate their ends, a loose connection between thecross-piece and the members comprising a loop on each member in whichthe end of the cross-piece ts in abutting relation with the member, andcrossed tensioning rods extending from the opposite ends of saidcross-piece to said members, whereby a. rigid truss structure is formed.

9. A saw frame comprising spaced mem-A bers, a cross-piece engaging'said members intermediate their ends, a loose connection between thecross-piece and the members comprising a loopon each member in which theend of the cross-piece lits in abutting relation with the member, andcrossed tensioning rods extending from the opposite ends of saidcross-piece to said members, one of said rods, having a turn-buckle fortensioning,` a. saw blade supported by said members.' y

l0. A saw frame comprising spaced members adapted to support a saw bladetherebetween, and a truss 'structure connecting said members in spacedrelation to the bla-de., said structure comprising a cross-piece adaptedto abut both said members, and means connecting both ends of saidcross-piece to each member including loop encircling each member and theadjacent end of the crosspiece, and a tensioning rod extending from eachmember to the end of the cross-piece remote therefrom.
